How to build?
Before we move onward to a DIY assemblage of the grow light systems, prerequisite knowledge of some terms associated with the lighting system, plant response to the types of light arrangements, and the equipment in use is necessary. Let’s have a brief about them.
Light possesses several features that affect the growth and development of plants including the intensity and the quality of light, uniformity and angle, brightness and direction that determine the process of photosynthesis and physiological processes. Chlorophyll is the driving force in photosynthesis that absorbs the wavelength of varying intensities from 400 nanometers to 700 nanometers often called PAR or PPFD with its peak absorption from 600-700 nm in the red and 400-500 nm in blue wavelength of light. PPFD is measured in μmol m-2 s-1 that is an outcome of the DLI-Daily Light integral and period of light by the source in 24 hours and is directly connected with the production of biomass by absorption of nutrients and water by the plants in that time.
The quality of light is the combination of the spectrum that enables different processes of growth and development in plants along with controlling the plant’s metabolic activities that concentrate on the quality of the product like color, taste, and maturity by maintaining it genetic and phenotypic characteristics.
Ultra Violet Spectrum (200-400 nm): It reduces the growth of fungus and is responsible for inducing resistance in the plants against diseases and pests along with stimulating pigmentation in leaves for further vegetative growth.
Blue Spectrum (400–500 nm): It controls stomatal opening in the leaves, helps in the vegetative growth stimulation and foliage development.
Green Spectrum (500–600 nm): It controls stomatal closing and maintains a balance of the moisture in the plant tissues while initiates photosynthesis in the deep tissue of leaves.
Red Spectrum (600–700 nm): It controls stem elongation, internodal distances, and hormones that control pollination and fertility of the plants.
Far-red Spectrum (700– 800 nm): It controls stem elongation, induces flowering, and the maturity processes.
#1 LED Drivers
LEDs perform better under low voltage so AC needs to be converted to a stable DC for their smooth functioning. DC to DC converters is best to drive them with the step-down options and regulators that make them efficient and energy saving. The drivers with the low DC input are preferred over AC drivers with a minimum output of 5 Volts and 5 Amperes.
#2 Heat Dissipation
The LEDs are generally associated with producing low heat that is controlled through active and passive heat sink methods. Heat dissipation is generally controlled through aluminum sinks in the passive cooling system while in the active heat sinks additional airflow is maintained using extra exhaust fans to keep the system cool and to avoid high temperatures.
#3 Dimmable options
LED light dimmers are an effective technique to control the brightness options at the different stages of the plant’s need. Another option is to install pulse-width modulation switch to the source and program it to switch up and down for the brightness control using a sensor or an analog dimmer can also be used instead of PWM switch that needs constant attention of the growers for brightness control.
DIY Installation for Panel
The first step is to ensure that each LED is connected in series with the MOSFET. All the power that comes to these LEDs will be controlled by utilizing Arduino PWM (Pulse width modulation) pin. The Arduino helps in complete separate control for all the different LED colors and thus helps in maintaining the required lighting. All the LEDs of a single color should be connected in series in the form of an array. Different LEDs’ types should be joined in separate PWM pins of Arduino.
This separate Arduino connection comes handy when you want to leave room for further adjustment or want to add more LED depending upon the requirement. The LEDs produces heat with light too, to overcome this issue, all the LEDs are held in place with the thermal tape in an Aluminum heat sink. This helps in even heat distribution and helps to avoid overheating.
The LEDs are further connected with a power supply with the help of a voltage regulator. The voltage regulator, here, helps in supplying a smooth and thorough voltage to the LEDs, ensuring the smooth and uniform running of the LEDs.
For the best quality of light, all the LEDs should be placed evenly over the surface. It is better to draw a diagram before going for the physical installation so that all the steps are carried out proficiently without hassle. The successful completion of a diagram will help you to connect all accessories and drivers more precisely.
